77.76MHz VCXO

General Description

Features

The DS4077 is an integrated voltage-controlled crystal

oscillator (VCXO) module designed to provide reference

clock generation in base stations, telecom/datacom, and

wireless applications. The DS4077 is developed using a

fundamental quartz crystal plus a unique integrated cir-

cuit design. The internal fundamental quartz crystal

determines the frequency of operation. Custom frequen-

cies are available. Contact the factory for availability.

♦ LVCMOS Output Buffer

The DS4077 is designed for use with applications requir-

ing low phase noise and jitter. Jitter performance of bet-

ter than 1ps RMS is achieved over the 12kHz to 80MHz

range. Phase noise performance of better than

-130dBc/Hz at 1kHz is achieved with this design.
